Kristin Cavallari and Jay Cutler engagement back on

Kristin Cavallari is tweeting that her engagement with Bears quarterback Jay Cutler is back on.

From her Twitter account just before noon: "This time its official..Jay and I are engaged again ."

The couple was engaged earlier this year, but in July, after 10 months, they announced it was suddenly over, even returning gifts already bought from their wedding registry. In early October, however, Cutler made an appearance in the audience of "Dancing With the Stars" while Cavallari was a contestant, sparking talk that the two were sorting out their differences.

In recent weeks Cutler and Cavallari have gone public again. Cutler tweeted on Nov. 11: "Dinner date night with @KristinCav. She loves her creamed spinach."
